Then you have the problem or the rear trailer's brakes locking and smoking the tires(less weight on the rear trailer), and more serious problem will happen when you going down a grade on a 35mph curve, brakes are glazing and smoking and your rear axle is locking up. You are actually relieved when you reach the bottom in one piece.

What ever gear you use to climb the hill should be used or one lower to come down and light steady pressure all the way to the bottom.

It's not an old timer or newbie thing, it's a going to fast thing along with common sense. It's really not our fault, they (was on my written part of my CDL test...... I'm a "newbie" I remember my CDL test)....... teach us to: Proper Braking Technique Remember: The use of brakes on a long and/or steep downgrade is only a supplement to the braking effect of the engine. Once the vehicle is in the proper low gear, the following is a proper braking technique. 1. Apply the brakes just hard enough to feel a definite slowdown. 2. When your speed has been reduced to approximately 5 m.p.h. below your “safe” speed, release the brakes. (This brake application should last for about three (3) seconds.) 3. When your speed has increased to your “safe” speed, repeat steps 1 and 2. For example, if your “safe” speed is 40 m.p.h., you would not apply the brakes until your speed reaches 40 m.p.h. You now apply the brakes hard enough to gradually reduce your speed to 35 m.p.h. and then release the brakes. Repeat this as often as necessary until you have reached the end of the downgrade. I really hope your not training "newbies" to drive.

Thanks for the reminder ben45750.

Totally agree,I would never trust some mechanic with my life when it comes to adjusting brakes I do them,and from your post I don't feel that your way of braking is correct,if I remember correctly you stated you had them smoking a few times.....I am always maxed out on weight and use the method I described and never have brakes smoking,proper gear selection and light brake pressure will always get you to the bottom.
